Definitions

  • the invention relates to a container with a pressure compensation device consisting of a container body, a container lid and at least one closure element consisting essentially of a threaded bolt, by means of which the container lid can be fixed on the container body.
  • spring safety valves are known. These work on the principle that a sealing cone is raised against the force of a spring. There are different designs here, which differ in the articulation of the sealing cone or its kinematics. In the known spring safety valves, the valve is opened in that the internal pressure and the force associated therewith overcomes the counterpressure of the spring which presses the sealing cone into its seat.
  • this principle has the disadvantage that such safety valves are more or less directly connected to the ingredients, especially if the structural conditions do not permit any other solution. If the valves of this type are used, for example, in special waste containers, they must be mounted on the lid of the respective container in order to enable proper functioning.
  • the spring safety valves also have the disadvantage that they are very susceptible to contamination. Another disadvantage is that they are expensive to build and are therefore very expensive to purchase if they are to work in small pressure areas. Furthermore, if a container is retrofitted accordingly, it often has to be structurally changed.
  • rupture disks Another known system for avoiding internal pressures is the so-called rupture disks. These rupture disks consist of a membrane with a much thinner material than other system parts. If there is now a negative pressure or positive pressure in the container, the membrane deforms in such a way that it bursts when a previously defined pressure is exceeded. Since even slight effects of corrosion, which are insignificant for other components, would lead to premature bursting in the case of a rupture disc, these are always made of corrosion-resistant materials, e.g. Monell, tantalum or VA steel. The disadvantage of this system is that the rupture discs are destroyed after a single response. In addition, the bursting of such a rupture disc can e.g. cause the material contained in the container to escape during transport of the container.
  • this object is achieved on the basis of a generic container by the characterizing part of claim 1.
  • the closure element for the container lid which essentially consists of a threaded bolt, is screwed over a head part, i.e. supported by a common part of the bolt against a spring which is arranged in a support element.
  • the support element is articulated on the container body or on the container lid or engages there.
  • the container lid can be fixed relative to the container body by means of a nut rotatably seated on the threaded bolt, for example a wing nut.
  • the threaded bolt that can be screwed to the lid for example, is connected to the container body via a spring.
  • the support element can consist of a U-shaped bracket, the free ends of which are pivoted on a bolt arranged on the container body.
  • the threaded bolt can be pivoted into a slot on the cover-side tab and can be fixed there via the nut.
  • a lock nut or a plurality of lock nuts can be screwed onto the threaded bolt in such a way that the tab can be clamped between them and the nut. This ensures that the spring is not over-tensioned by tightening the nut when closing the container lid.
  • the spring can advantageously be a plate spring.
  • a plurality of threaded bolts can be arranged uniformly distributed over the circumference of the container lid.
  • the container lid can also be pivoted on the opening edge of the container body via a swivel joint.
  • a sealing rubber is advantageously arranged in the container lid, which is pressed into the edge of the container body when the container lid is closed.
  • the invention further relates to a closure element for use in a container of the type described above.
  • This closure element consists of a threaded bolt which is supported via its head part against a spring which is arranged in a support element.
  • This closure element can be used in conventional pressure containers without further structural changes to these containers in order to convert them into containers with a pressure compensation device.
  • the container 10 comprises a container lid 14 which is placed on a container body, not shown in detail in FIG. 1, preferably a waste container body.
  • the container body is designated by 12 in FIG.
  • the container body 12 has a welded-on edge 38, to which a container lid 14 is articulated by means of a swivel joint 44 known per se.
  • the container lid 14 will be fixed to the container body 12 via six threaded bolts 16 uniformly distributed over the circumference and wing nuts 24 cooperating with them.
  • a U-shaped bracket 22 forming a support element is pivotally connected to the container body 12 via a bolt 40 via a U-shaped holder 42.
  • a plate spring 20 is arranged in the support element 23, at the free end of which a head 18 of the threaded bolt 16 is supported.
  • the threaded bolt 16 is inserted in the manner shown in Figure 2 through a corresponding hole in the support member 22.
  • two lock nuts 30 and 32 are screwed, which are secured against each other via a tack point 34.
  • the threaded bolt can be pivoted into a slot 26 of a tab 28 welded onto the container lid 14.
  • the lock nuts 30 and 32 or a washer resting thereon bear directly against the tab 28 from below.
  • the wing nut 24, which comes to rest on the tab 28, is screwed onto the free end of the threaded bolt 16.
  • a sealing rubber 36 provided in the container lid 14 is pressed onto the edge 38 of the container body 12 (see FIG. 2). If the wing nut 24 of the respective container closure is loosened, the entire container closure can be pivoted about the pivot axis 40. The cover 14 can then be opened by pivoting about the articulation axis 44.
  • the cover 14 presses against the force of the plate spring 20 via the tab 28 and the threaded bolt 16 Force on the lid is greater than force opposed by the spring 20 or a plurality of springs 20, the lid 14 is raised slightly. This creates a gap between the container edge 38 and the sealing rubber 36, so that pressure equalization with the surrounding atmosphere is made possible. As soon as the excess pressure is released, the lid lowers again.
  • the pressure point with which the lid is raised can be adjusted by turning the lock nut 30 or 32.
  • it can be set to an opening pressure of 0.3 to 0.5 bar.
